C3_W1_assignment typos

Some minor typos from assignment 1.

In the course week 1 page, the section title for the assignment misspells the word “assignment” as “Assingment”.

In section 2.1, there is code that prints the string “The dataset generated from the generator functions is not identical to the expect one.”, but here “expect” should probably be “expected”.

In exercise 4, there is a cell that tests the pdf_uniform function. That cells prints 4 lines of text, but the “expected output” only includes 3 lines of test.

Thanks! I’ve fixed every flagged issue. Please remember you may need to refresh your workspace to see the changes.
